Exciton-polaritons and condensation
Exciton-polariton condensates are one of the most promising routes to realize quantum optoelectronic devices at room temperature. Currently, there exists no chemical foundation on how to design polaritons and condensates with desirable quantum properties, such as coherence times. QUEST Lab tunes excitons in organic, inorganic, and hybrid material systems to control condensate formation and propagation. We explore fundamental concepts such as physical factors determining particle interactions and condensation thresholds. We are also building concept-testing device architectures to make controllable exciton-polariton platforms that could be adopted for various applications in energy harvesting, information science, light emission, and sensing.
Tuning exciton–polaritons
We go beyond conventional Si/III-V semiconductors and design tunable excitonic materials systems, such as 2D perovskites. These platforms allow for control over key polariton properties through doping and engineering their structures. We integrate these custom excitonic materials into tunable devices to manipulate the polariton potential landscape, allowing for precise control over polariton propagation.
Design the matter component
Chemical composition and local structure shape the exciton that couples to light. By designing semiconductor materials and microcavity environments, we seek polaritons with controllable properties and new routes to room temperature quantum phenomena
Probe nonlinear dynamics
Nonlinear and time-resolved spectroscopy reveals how carriers, interfaces, and local fields shape emission and energy flow. We also explore how polariton states can influence reaction pathways, electronic structure, and energy-transfer rates.
